Grandpa Sweet Fist

Sweet Fist was a joke. He has no superpowers. He was merely a guy with some martial arts who dress up in a costume with a candy theme. He said stupid things like 'Sweet Dreams' and 'Choco Punch' when fighting and was an embrassment to the supervillain community. He has just been released after spending twenty years in prison. Now he got a System, and the System informed the villain that he had many kids and even some grandchildren. The System want the villain to reunite with his family. Failure means death. Only one problem; Sweet Fist never knew he had kids. How was a bad guy supposed to reunite with a family he never knew existed?
